sell : precipitated calcium carbonate

Usage: Fillers of plastic such as for plastic, rubber, paper, polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), ABS, etc. Characteristic: 1) Identical grain size, low oil absorption value 2) To reduce the cost of products; to make products have good foamed effect 3) To enhance hardness, rigidity, size stability, fire-retardantness, glossiness of products 4) Calcium carbonate is used for high polymer material to improve the craftwork of processing and enhance the mechanics and hot stability of products; It can reduce the cost with the enhancement of dispersibility and compatibility Specifications: 1) Light calcium carbonate 2) Main Constituent (CaCO3): ≥96% 3) PH (10% solid quit): 8.0 - 10.0%, 105oC 4) Volatile: ≤0.50% 5) Insoluble substance in hydrochloric acid: ≤ 0.3% 6) Settling value: ≥2.2ml/g 7) Average grain: 1.5 - 3.5μm 8) Fe: ≤0.10% 9) Mn: ≤0.010% 10) Screenings 125μm: ≤0.010%, 45μ: ≤0.40% 11) Whiteness (R457): ≥94 12) Appearance: powder Inner packing: with plastic pellicle Outer packing: plastic knitted sack Currency: USD
